Resource recovery can be enabled by changes in government policy and regulation, circular economy infrastructure such as improved 'binfrastructure' to promote source separation and waste collection, reuse and recycling, [5] innovative circular business models, [6] and valuing materials and products in terms of their economic but also their social and environmental costs and benefits. [7]
Co-processing is the use of waste as raw material, or as a source of energy, or both to replace natural mineral resources (material recycling) and fossil fuels such as coal, petroleum and gas (energy recovery) in industrial processes, mainly in energy intensive industries (EII) such as cement, lime, steel, glass, and power generation.
A single-stream system is a complex network of machinery that uses a combination of newer and older technologies to sort materials for recycling, including PET, HDPE, aluminum, tin cans, cardboard and paper. List of equipment used in a single-stream system: Back Scraping Drum: spreads materials out on a conveyor belt
Incineration, the combustion of organic material such as waste with energy recovery, is the most common WtE implementation. All new WtE plants in OECD countries incinerating waste (residual MSW, commercial, industrial or RDF) must meet strict emission standards, including those on nitrogen oxides (NO x), sulphur dioxide (SO 2), heavy metals and dioxins.
The circular economy is a framework of three principles, driven by design: eliminating waste and pollution, keeping products and materials in use, and regenerating natural systems. [6] It is based increasingly on renewable energy and materials, and it is accelerated by digital innovation.
Landfill gas utilization and municipal composting can capture and use the organic nutrients. [6] Food waste collected from non-industrial sources is harder to use, because it often has much greater diversity than other sources of waste—different locations and different windows of time produce very different compositions of material, making it ...
Flushing our waste is, well, wasteful, accounting for nearly a third of indoor water use in US homes, according to the Environmental Protection Agency (EPA). In many parts of the world, the use of ...
Within the concept of a circular economy in sanitation, an alternative term that is being used is "resource flows". [4]: 10 The final outputs from the sanitation treatment systems can be called "reuse products" or "other outputs". [4]: 10 These reuse products are general fertilizers, soil conditioners, biomass, water, or energy.
